Should get 2020 screw with end bearings and machined for about £200.
You are probably right but I mentioned 2005 because 1605 was mentioned before, which I don't think is very good at that length due to the risk of deflation. 2005 is considerably stronger but of course 2010 will be even better speed vise. I didn't know that you can get 2020 but sure that would be even better at this length.
